A little while ago PowerColor released a new SKU from the popular Radeon HD 5770 lineup of products; in fact they made an actual single slot version of this card, allowing you to go for multi-GPU setups much easier as it saves a lot of space.

The new cards are clocked at reference speeds as the new single slot coolers obviously have a little less cooling capacity compared to the dual-slot version. Today we'll take a total of four of these cards and see what they'll do setup in multi-GPU-mode, CrossfireX.

See the Radeon HD 5770 as tested today can be purchased for roughly 150 EUR a pop these days, three of them with one Gigabyte of graphics memory each could open up a can of performance, easily beating the most high-end CPUs.

Well, to find that out we requested four of these cards from Power Color to see what happens.
